*     ****************************************************************  *;
*	This readme file provides information indicating how to 	*;
*	replicate the results in Golder, Matt. 2006. "Presidential 	*;
*	Coattails and Legislative Fragmentation." American Journal of 	*;
*	Political Science.						*;
*									*;
*	1. There are three primary datasets:   				*;
*									*;
*	coxappend.dta - these are data from Amorim Neto & Cox (1997)	*;
*									*;
*	legislative_newp.dta - these are data on legislative 		*;
*	elections using slightly updated data from Golder (2005).       *;
*									*;
*	presidential_new.dta - these are data on legislative 		*;
*	elections using slightly updated data from Golder (2005).       *;
*									*;
*									*;
*									*;
*	2. There are four do-files that replicate all results in the 	*;
*	AJPS paper. 							*;								*;
*									*;
*	electoral.do - this replicates results in Table 1.		*;
*									*;
*	pres_runoff.do - this replicates results in Tables 2 and 3.	*;
*									*;
*	presfig.d0 - this replicates the figures in Figure 1.		*;
*									*;
*	electoral_enep.do - indicates that the effective number of 	*;
*	parties in presidential regimes using runoffs is significantly 	*;
*	higher than in presidential regimes employing plurality rule.   *;
*       This result is mentioned in the conclusion of the AJPS paper. 	*;
*									*;
*									*;
*									*;         
*	3. There are several additional do-files that conduct extra	*;
*	analyses - robustness checks requested by the reviewers. 	*;
*									*;
*	electoral_measurement.do - this shows that nothing changes with	*;
*	my inferences if I do not drop those observations where the	*;
*	effective number of electoral parties is measured with error 	*;
*	i.e. those observations with the "other" category > 15%		*;
*									*;
*	electoral_upper.do - this shows that nothing changes with my	*;
*	inferences if I take account of upper tier seats.		*;
*									*;
*	lcross_extra.do - this shows that nothing changes with my 	*;
*	inferences if I use 1980, 1990, or 2000 instead of 1985 and 	*;
*	1995 for my cross-sections for Table 1.	This uses dataset	*;
*	lcross_extra.dta.						*;
*									*;
*	press_runoff_extra.do - this shows that nothing changes with my *;
*	inferences if I use 1980, 1990, or 2000 instead of 1985 and 	*;
*	1995 for my cross-sections for Tables 2 and 3. This uses dataset*;
*	pcross_extra.dta.				  		*;
*									*;
*	pres_runoff_US.do - this shows that nothing changes with my	*;
*	inferences if I include countries that employ electoral college	*;
*	or STV as non-runoff systems for Tables 2 and 3.		*;
*									*;
*	pres_runoff_endogeneity.do - this addresses the issue as to 	*;
*	whether presidential runoffs might be endogenous to the number	*;
*	of presidential candidates. Results suggests that nothing 	*;
*	changes with my inferences.					*;
*									*;
*	electoral_xtpcse.do - this shows that my inferences do not 	*;
*	change if I use XTPCSE or lagged dependent variables.		*;
*									*;
*	pres_runoff_xtpcse.do - this shows that my inferences do not 	*;
*	change if I use XTPCSE or lagged dependent variables.		*;
*									*;
*	presfig_xtpcse.do - this creates figures equivalent to Figure 1	*;
*	using XTPCSE.							*;
